Status: Adopted

Effective date: 2026-08-10

Creates a documented threshold for admitting works to the permanent record and for recording any later removal from institutional custody.

## Provisions

1. Accession requires confirmed token identity, current custody, a traceable custody event, a credit line, rights metadata, and an initial preservation assessment.
2. Selection, acquisition, custody, and accession are distinct states. A selected or held work is not accessioned until its record is published.
3. Accession identifiers are permanent and are never reassigned.
4. A disposal, transfer, loss of access, or mandate-based removal does not erase the accession record. Its custody status and reason are revised with an audit entry.
5. Deaccession decisions must identify authority, rationale, destination when public, and whether retained research or media records remain.
6. No work in the initial pilot is approved for deaccession by this policy.
